Question

此问题与this post有关。

如果计数器看起来像这样，还有一个问题：

"\MSSQL`$SQLMET:Databases($DatabaseName)\Log Bytes Flushed/sec"

我收到此错误：

The \MSSQL$SQLMET:Databases(fee_monsson)\Log Bytes Flushed/sec performance
counter path  is not valid.
At C:\Users\MihaiDarzanGefee\Desktop\sql-perfmon.ps1:49 char:12
+ Get-Counter <<<<  -Counter $counters -SampleInterval 1 -MaxSamples 3600 | 
    + CategoryInfo          : InvalidResult: (:) [Get-Counter], Exception
    + FullyQualifiedErrorId : CounterPathIsInvalid,Microsoft.PowerShell.Commands.GetCounterCommand

如果我转到perfmon，我会找到计数器\MSSQL$SQLMET:Databases(fee_monsson)\Log Bytes Flushed/sec，所以我无法理解错误。

代码是：

<#
    .SYNOPSIS

    .DESCRIPTION

必须以管理员身份运行powershell脚本（例如：右键单击powershell.exe并单击“以管理员身份运行”，而不仅仅是从管理员帐户运行它）。它抓取性能计数器，而不是数据库中的数据，所以它需要适当的权限。

性能计数器路径无效
